Five sites that should support OpenID

OpenStreetMap and Last.fm both pose an interesting problem in that as well as a web application they also use desktop apps. In OpenStreetMap's case their editors like JOSM need to authenticate against the REST-based API, and in Last.fm's case the Audioscrobbler plugin needs to authenticate with the server when it reports what tracks you're listening to. That something is hard doesn't mean it's not worth doing, though!

Just an idea...

Well, this is just an idea about how to overcome this problem... How about writing an openid server that has a backend to which I can connect, maybe jabber backend or something like that? This way I can use an applet that connects to the backend and notifies me with a popup when someone (hopefully myself) wants to get authenticated.
